XPL, for expert's programming language[1] is a programming language based on PL/I, a portable one-pass compiler written in its own language, and a parser generator tool for easily implementing similar compilers for other languages.

The XPL programming language is a derivative of PL/I designed for compiler writing. XPL was first announced at the 1968 FJCC in San Francisco, CA. (See McKeeman, Horning, Nelson and Wortman below.) XPL is the name of both the programming language and the compiler generator system (or TWS: translator writing system) based on the language.

Jan 8, 2021 · The XPL0 Programming Language. This site provides distributions of XPL0 that run under DOS and early versions of Windows, up through 32-bit Windows 7. Recent 64-bit versions of Windows must use something like DOSBox to run these programs.

Jul 29, 2024 · XPL, for expert's programming language is a programming language based on PL/I, a portable one-pass compiler written in its own language, and a parser generator tool for easily implementing similar compilers for other languages.

XPL, or eXtensible Programming Language, is a language that emphasizes adaptability and extensibility. Designed with the principle of flexibility in mind, XPL allows developers to create new syntactic constructs and tailor the language to specific problem domains.

The XPL language is similar to PL/I, but is not PL/I. Major differences between XPL and PL/I are indicated in the text. A program is a sequence of statements terminated by the special symbol eof. A complete XPL program is equivalent to the body of a PL/I main procedure.

XPL is a programming language based on PL/I, a portable one-pass compiler written in its own language, and a parser generator tool for easily implementing similar compilers for other languages. XPL was designed in 1967 as a way to teach compiler design principles and as starting point for students to build compilers for their own languages.

XPL was one of the first high level languages that implemented automatic garbage collection (for strings only). The book and the authors approach can be considered as the early example of literary programming but the term was coined much later by Donald Knuth.

Jul 6, 2000 · XPL was developed as a versatile programming language, designed to handle a variety of tasks by integrating XML as a core element. The language's ability to use XML for controlling data flow, message-passing formats, and as a universal data container made it an innovative tool for developers.
